After five games in the Florida State League, Mets infielder T.J. Rivera‘s rehab assignment has been transferred to Triple-A Las Vegas.

In 19 at-bats with the St. Lucie Mets, he hit safely four times, including a double, with an RBI and three strikeouts. Rivera has been on the disabled list since undergoing surgery to repair a torn ulnar collateral ligament in September.

The 29-year-old is expected to suit up for the 51s beginning on Friday.

Las Vegas made some other roster changes as they returned from the All-Star break on Thursday:

Chris Beck was sent outright to the 51s after clearing waivers. The right-hander was designated for assignment by the Mets between games of Monday’s doubleheader. Beck had the right to refuse the outright assignment and instead elect free agency, but he’ll instead remain with the organization and make that decision following the regular season. After he was claimed off waivers from the Chicago White Sox on June 13, Beck recorded a 5.23 ERA six outings with the Mets.

Scott Copeland and Harol Gonzalez were transferred to Binghamton after making spot starts for Las Vegas. Copeland, who made one appearance for the Mets on May 31 and was promptly designated for assignment, allowed one earned run over six innings for the 51s on July 6 as he continues to serve as organizational depth. Gonzalez, 23, effectively receives a promotion-by-demotion, as he joins the Rumble Ponies after one solid start in Triple-A. In 73.1 innings with St. Lucie, he posted a 2.82 ERA.

Phillip Evans, a former member of the major league 40-man roster, was activated off the disabled list. According to reports, Evans contracted an infection in his leg and was hospitalized for treatment.
